INSTALLING YOUR AP445-401

OPERATION  
7
Step 1. Determine a good location for placing the  
AP445-401. For best results, choose a  
location that minimizes cable lengths.  
7.1 FRONT PANEL OPERATION  
Front panel control is available using push buttons  
with LED indicators. The front panel may be used  
to select the input, adjust image properties, adjust  
the volume and select the output resolution.  
Step 2. Connect a cable from each video source  
to its corresponding video input connector  
on the AP445-401. The Component and  
Composite video input connectors are  
BNC type. If using RCA cables, use the  
RCA to BNC adapters provided with the  
unit.  
The front panel buttons may be locked using  
RS-232 control. If pressing the buttons on the front  
panel has no effect, use RS-232 control to verify  
the front panel is not locked.  
7.1.1 SELECTING THE INPUT  
Step 3. Connect a cable from each audio source  
to its corresponding input. Take care to  
ensure the video and audio inputs match.  
The control buttons for input selection are on  
the left hand side of the unit. Selecting the input  
will make that image available on the  
RGBHV/YPbPr Output.  
Step 4. Connect the video output connector of the  
AP445-401 to the display device with a  
VGA type cable for RGBHV displays or a  
YPbPr cable for Component Video.  
In order to make the input signal on the S-Video  
input available on the output, press the S-VID  
button. The input will be selected and the LED  
will turn on.  
Step 5. Determine which audio output is to be  
used. Either the adjustable balanced  
stereo using the terminal block or the  
fixed unbalanced stereo using the 3.5mm  
jack.  
Step 6. Connect the audio output connector of the  
AP445-401 to the speakers or amplifier  
using the appropriate audio cable.  
Step 7. Connect the AP445-401 to AC power.  
Then unit is now operational.  
Step 8. The default input selection is the S-Video  
port. In order to change the input to other  
than Composite Video, use the front panel  
buttons or RS-232 control.  
S-VIDEO  
For example, press the S-VID button on the  
front panel to make the S-VID input connected  
to the rear of the unit active. The main  
RGBHV/YCbCr output will now display the  
image on the S-VID input.  
NOTE: RS-232 operation: Use AVSnap or  
other RS-232 communication software.  
Follow the instructions defined in section  
7.3 for the IN command.  
Step 9. Select the correct output resolution mode  
for the display device.  
Step 10. Adjust the display properties for optimal  
image quality.

SPECIAL APPLICATION  
7.1.2 MAKING PICTURE ADJUSTMENTS  
7.2 RS-232 CONTROL  
There are controls available for the following  
picture properties: color, contrast, brightness,  
hue and sharpness. Pressing one of these  
buttons will make that property the active  
control. Then, use the + and – buttons to adjust  
the image.  
The AP445-401 has many advanced remote  
control capabilities, which are accessible through  
standard RS-232 communication. The actual  
controlling can be accomplished through  
a
computer control system or any other device  
capable of sending RS-232 commands.  
7.2.1 RS-232 INTERFACE  
-
+
The RS-232 commands, for the AP445-401, are  
in a simple ASCII character format.  
1. Square brackets “[ ]” are part of the  
command.  
2. Use uppercase letters for all commands.  
BRIGHTNESS  
INCREASE/  
DECREASE  
After processing a command, an [OK] or [ERR]  
will be returned as feedback if "F" is included at  
the end of a command string.  
For example, press the BRIGHT button to make  
the brightness setting the active function. Then  
use the plus and minus buttons to increase or  
decrease the brightness level as necessary.  
Commands ending in "S" will be saved into  
memory. Commands not ending in "S" will still  
be executed but will not be restored when the  
system is reset or powered off then on.  
7.1.3 CHANGING THE OUTPUT RESOLUTION  
The output resolution is controlled using the  
OUTPUT MODE button. Each time the button is  
pressed, the next resolution is selected.  
Repeatedly pressing the button will cycle  
through all the available resolutions.  
7.3 DESCRIPTION OF COMMANDS  
The default unit ID is zero, but may be set to a  
value from 0 to 99. In single unit operation,  
commands may be sent without the unit  
identifier. Unit ID 0 should be used for single  
unit operation.  
-
+
If multiple AP445-401’s are connected to the  
same communication port, the units may be  
controlled two ways. In order to control all the  
units the same, commands may be sent without  
the unit identifier. Commands sent without the  
unit identifier will be executed by all  
AP445-401’s.  
OUTPUT MODE/  
RESOLUTION  
Individual control is accomplished by first  
assigning each unit a unique ID number. Then  
each unit may be controlled individually by  
including the unit identifier at the end of each  
command string.  
7.1.4 ADJUSTING THE VOLUME  
The audio gain is controlled just like the video  
picture adjustments. First, press the AUDIO  
button on the panel. Then, use the plus and  
minus buttons to adjust the volume.
